Andrew’s Graph Project My numerical data.. How many times have you gone to the Dome in the past year? 3/31-4/5 Line Graph number of people How many times gone to the dome in 1 year 10 8 6 4 2 0 1 2 3 4 5 how many times 6 7 8 Least Effective Because… The Line graph is the least effective because line graphs really help when you show a dramatic change. I used this line graph to show how many times people in my class have gone to the Dome in the past year, however the graph shows the lines going up and down and this doesn’t really help, it just looks like a graph when something changes. This line graph would be very effective for a graph to show sales in the marketing business. Line graphs are a good graph they just didn’t fit into this sort of data. Pie Graph How many times gone to the Dome in the past year Times gone to the Dome in one year. 0 1 to 2 3 to 4 5 to 6 7 to 8 9 and up Column Graph number of people how many times gone to the Dome in a year 9 8 7 6 5 4 3 2 1 0 0 1 to 2 3 to 4 5 to 6 7 to 8 number of times gone to Dome 9 and up Most Effective This is the most effective graph because I feel this is easier to read and easier to follow. This bar graph is much easier to follow than the line graph and a little bit easier to follow than the pie graph. This helps with my set of data because it is the most efficient and works better and is easier to read and follow than the other two graphs. “Typical” For My Data My median for my set of data is 3. This helps me find what was the middle amount of numbers. How I found my median in this set of data, was with the range of numbers. For example, the range was 1-2 and 3 people said 1-2. I would put 1 three times and 2 three times. My mean is 5.1, this helps me kind of find the average, even though the mean is not the average, it is close to it. No values share the same amount, therefore there is no mode. In graphing there is sometimes an outlier, this happened in my data. In my data the outlier is the one with times gone to the Dome with one vote gone 9 times. This effected my data because my median would not share a value with another if there were 30 numbers not 31. Out of the mean, median, and mode, the one that is the most effective I think is the mean. I think the mean is most effective because this helps find the average of times gone to the Dome in my class. This helps with what the main amount gone is. The mean, and the bar graph are the most effective with my set of data.
